Coal trains are composed of approximately 120 rail cars, resulting in an average of 60,000–420,000 lbs. of coal lost per train each trip. A massive increase in rail traffic and longer trains are expected in the future should new hotly contested coal export terminals be built in Washington and Oregon.
Introduction. Oregon ranks 42nd out of the 50 states in terms of coal energy production. However, nearly 40% of Oregon's power comes from coal, half of which is produced out of state, primarily the Powder River Basin in Wyoming and Montana.
Coal ash is the collective term for the various solid remnants left over from burning the black rock to produce electricity at more than 500 power plants nationwide. The ash amounts to dirty stuff, replete with toxic constituents — arsenic, chromium, lead, mercury, and many others — that can wreak havoc on the environment and human health.
